Depending on the disaster situation, it is necessary to prepare in advance a plan that considers the use of the corridor space for medical aid stations in consideration of the possibility that areas originally intended for such purposes may not be useable. We conducted a survey using a model in order to gain knowledge about the facility design that makes it easy to construct a medical aid station in the corridor space of a hospital. The survey was aimed at clarifying the characteristics of the set-up contents and problems during set up when accepting casualties in planned corridor space.
